MIOHAL KENNEDY, OF POMPEY, NEW YORK.

PROPELL-ING MECHANISM FOR ICE-BOATS.

SPECIFICATION forming part of Letters Patent N 0. 613,281, dated November 1, 1898.

Application filed April 18, 1898.

To all whom it may concern:

Be it known that I, MIoHAL KENNEDY, a subject of the Queen of Great Britain, residing at Pompey, in the county of Onondaga, in the State of New York, have invented new and usefulImprovements in PropellingMechanism for Ice-Boats, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in devices for propelling ice-boats over snow and ice.

My object is to produce a device for propelling an ice-boat over the snow and ice by means of pedals; and to that end my invention consists in mounting the boat or body upon runners and providing its forward end with guide-runners suitably connected to handlebars and providing the rear end with propellers, which are adapted to come in contact with the ice and propel the boat along; and to that end myinvention consists in the several new and novel features of construction and combination of parts, which are hereinafter described and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings,in which Figure 1 shows a side view of my ice-boat complete, ready for use, the side, however, being broken away, so as to show the pedals mounted within. Fig. 2 shows a top plan view thereof, the bottom of the rear end concealing the transverse operating-shaft broken away. Fig. 3 is an enlarged view of the propelling mechanism. Fig. 4 is a detail of a portion of the pedal-arm, showing it incased in a sleeve to prevent water from getting within the boat through the slotway in which the said pedal-arm operates. Fig. 5 is an enlarged view of a ratchet-wheel mounted upon a transverse operating-shaft and showing the pedal-arm in engagement therewith. Fig. 6 is an edge view of the ratchet-wheel mounted on the operating-shaft, showing the dogs out of engagement. Fig. 7 is a similar view showing the dogs in engagement.

Similar letters and numerals of reference indicate corresponding parts.

desired and is mounted upon runners 1 centrally and is provided upon each side with guide-runners 2, which terminate at their upper ends in handles 3, the nose of said runners being adjustably pivoted at 4, as shown in Fig. 2. The handles or handle-bars 3 are connected together laterally by a bar 5, so that they will move simultaneously, and 6 is a brake or shoe mounted upon the forward end of the boat, on its under side, adapted to be operated by a rod 7, suitably pivoted and connected to a foot-piece 8.

' Within the boat is a framework 9, carrying a seat 10, and that part of the frame which supports the seat is provided with rearwardlyextending braces 11, supported at their lower end either upon the transverse operating-shaft 12 or in any other suitable manner.

The transverse operating-shaft 12 is mounted as shown and is provided with ratchetwheels 13, rigidly secured thereto, and 14 are pedal-arms mounted at their rear ends upon the shaft 12, the forward ends being provided with a pedal 15, and is provided with a sleeve 16, so as to prevent water, in case of immersion, from passing through the slotway 17, and between these two pedal-arms is mounted a belt 18, traveling upon rollers, as shown in Fig. 2, and are secured to the pedal-arms, so as to cause these pedal-arms to move simul taneously in opposite direction-that is, when the pedal upon one side is downward the opposite pedal is forced upward. The pedalarms 14 are provided with spring-actuated dogs 19, adapted to engage with the ratchetwheel 13, and 20 is a rod mounted on said pedal-arms 14, having an arm 21 at one end, which is adapted when the pedal-arm 14 is raised to engage with the arm 22 for the purpose of rotating it, thereby causing the said rod 20 to actuate the dogs 19 and throw them in engagement, as aforesaid. It will thus be seen that by the upward movement of the pedal-arm 14 the dogs will be held out of engagement with the ratchets; but as soon as it gets up to the point indicated by the dot= ted lines in Fig. 5 it will be tripped by the arm 22 and the dogs 19 will engage with said ratchet, so that by the downward movement of the pedal-arm the shaft 12 will be rotated. I do not, however, limit myself to this pre= cise construction of rotating the shaft 12, as it will be evident that it may be done in various ways.

Upon each side of the rear end of the shell or boat I mount a propelling mechanism, which consists of an arm 23, mounted upon the shaft 12 and adapted to be turned with it, and to the arm 23 is a piece 24, having its tip adapted to engage with the snow or ice, and 26 is an upright hinged thereto, having a pin 27, and 28 is a brace hinged to the arm 23 and the upright 26.

29 is a bracket secured to the outside of the boat, carrying a trackway 30, in which the pin 27 is adapted to travel, so that as the shaft 12 is rotated the pin 27 will travel in the trackway 30, so as to produce what I term a walking propelling mechanism.

31 is a lever suitably mounted and having a gooseneck 32 hinged to the piece 33, which is secured to the piece 24 adjacent to the tip 25, and 34 is a bracket suitably mounted, adapted to engage at one end with the arm 23 in its upward movement, so as to throw the lower end of the arm 31 to one side, so as to produce an upward movement upon the piece 33 to pull the tip 25 out of its bed in the ice and snow.

is a trackway in which the outer end of the pin 36 travels.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an ice-boat, the slotted supports placed upon opposite sides of the bow, and pivoted runners placed under the front end of the bow, combined with the handle-bars which are rigidly connected both to the runners and to each other, substantially as shown.

2. In an ice-boat, the pedal-arms, the boatframe having openings through which the pedal-arms extend, and the sleeves 16 which are secured to the frame around the openings and to the pedal-arms, substantially as described.

3. The pedal-arms, combined with an endless strap, and guiding-rollers around which the strap extends, and which strap serves to connect the pedal-arms together so that they will always move simultaneously, substantially as set forth.

4. The pedal-arms carrying pawls, and the driving-shaft provided with ratchet-wheels upon its ends, combined with the rods 20 mounted on the pedal-arms and provided with arms 21 at their front ends, the braces 11, and the arms 22 projecting downwardly therefrom, the arms 21 being adapted to be struck by the arms 22 for the purpose of operating the pawls, substantially as specified.

5. The driving -shaft- 12 provided with ratchet-wheels upon its end, the rods or arms 23 connected to the ends of the shaft, the rod 24 connected at its forward end to the rod or arm 23, the rods 26 connected to the rods 25 near their rear ends and provided with pins 27 at their upper ends, the arms 28 connecting the arms 23 and 26, the bracket 29 provided with a trackway 30, the rod 33 connected at its lower end near the rear end of the rod or arm 24, the rod 31, and the bracket 34 suitably mounted and adapted to engage at one end with the arm 23 so as to throw the lower end of the arm 31 to one side and produce an upward movement upon the rod 33, substantially as shown and described.

In witness whereof I have hereunto set my hand this 18th day of March, 1898.

MICHAL KENNEDY.

In presence of MARY A. FRANKLIN, HOWARD P. DENISON.
